st: RE: RE: RE: literal single quotes

No one suggested the first. `= char(96)' is needed
On the general idea, I happily accept that programmers want to avoid
ugly codes. But I have never found this device either necessary or
attractive. The underlying idea seems to be that of "storing" the macro
for later use, but you really don't need to code like that.

Thanks, Roger, Nick
Both suggestions work, but something like
. local bull = "count if char(96)tempchar(39) >0"
. `bull'
unknown function ()
r(133);
does not work.
. local lq = char(96)
. local rq = char(39)
. local bull = "count if `lq'temp`rq' >0"
. `bull'
334
(works)
. local bull "count if \`temp\' >0"
. `bull'
334
(works)
Nick - I see a legitimate need for this when you have a long expression
involving temporary variables or names that may make the code look ugly
if written out next to some other long statement.

This sounds like the urge for setting up a delayed evaluation, on which
my advice is
1. Use \` to insert a literal left quote if the urge is overwhelming.
2. Better, resist the urge. Rewrite your code so that you don't need to
do it.
This came up a few months ago, but I can't find my post. Martin Weiss
will probably remember it.

Can someone please tell me how to define a local macro that contains
literal single quotes? For example Suppose I want to do something like
local bull "count if `temp' > 0"
where `temp' is to be interpreted literally, not evaluated.
